PEA-HULLER.

SPECIFICATION forming part of Letters Patent No. 412,005, dated October l, 188g. Application filed October 13, 1838. Serial No. 288,015. (No model.)

To all whom it may concern,.-

Be it known that I, WILLIAM FURLoW SMITH, of Holton, in the county of Bibb and State of Georgia, and a citizen of thc Unit-cd States of America, have invented certain new and usefulImprovements in Iea-l'lullers and I do hereby declare the following to be a full, clear, and exact description of the invention, such as Will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to figures or letters of reference marked thereon, which form. a part of this specification.

' This invention relates to improvements in machinery for hulling or thrashing peas and other leguminous seeds, having for its object the supplying of a machine that will remove the entire contents of the pods without injuring the product by cracking or bruising the same, as is often the case in machines of this class as heretofore used.

The invention consists of means for breaking the pods and of separating the same from the seeds, the details ol which will he hereinafter fully set forth, and the parts thought to be new pointed out in the claim.

In the accompanying drawings, Figure 'l is a longitudinal section. Fig, 2 is a plan View. Fig. 3 is a orosssection. Fig. et is a longitudinal section of the plunger and closingchamber.

In the figures like reference-marks indicate corresponding parts in the several `."iews.

A is the supporting-frame, and Il the hopper, both of which may be of any desired construction compatible with its functions. The hopper B is secured in any desired manner to the breaker-chamber C, the opening from said hopper into said chamber being preferably adj usted by the leaves b, if in any Way, said leaves being operated to open or close the said opening by the screws h', which pass through the sides of the hopper at a point below the leaves b and at an angle at which they will bear upon said leaves.

In the central part of the breaker-chamber C is the reciprocating plunger D, which is guided by the rods (l, one of which is connected to the mechanism. for reciprocating said plunger I), preferably as shown, which is by a crank and pitman. In thc top edge of the plunger I) are the teeth Z,if desired, for the purpose of agitating the mass in the hopper, and in each side of said plunger are the teeth d', which are set closer together in cach row as the rows are nearer the bottom edge of the plunger, and the rows are also closer together, beth. for reasons that will bc hereinafter sci forth.. The pieces (7,, which correspond in shape on their edges to the shape of the breaker-chamber with which they come in contact, are fastened to each end of the plunger D, as shown in Figs. and 3, and have on the inner sides of. cach of them the pieces rZ", which prevent any pods from Working through. Without coming in contact with the breakers and fromdropping outside of thc iluc E, and at the same time brcalc all pods with which they come in contact in the same way as the pins.

The sides oi' thc breaker-chamber are provided with rows of teeth o, which pass between the rows of teeth in. the plunger I), cach row being sct thicker with spikes as the rows approach the betteln. A great advantage is gained by having these teeth so set both in the plunger l) and in the sides of the breakerchamber-namely7 the poils before breaking- Will readily enter between, the spikes in the top rows, which rows will., by the rcciprocation of the plunger, brcalc. the long pods into pieces short enough to allow them to proceed down through the machine, which process will be continued until the pods and seeds are separated. From the foregoing it will be readily seen that the pods will enter readily, but that no Whole pod will pass through the machine by any possible chance. 'lhc teeth 7/ and o may be set in any number of rows and as closely together in such rows as may bc found desirable, as the pods of some leguminous plants require to be brohien much finer before they will separare from the seeds than. others.

As soon. as the operation of completely breaking the pods and freeing the seeds shall have taken place the broken pods and seeds will drop by gravity through the ilue E into the blast-fine F, where the saine will. be sepa rated, the seeds dropping throi'igh the screen IOG f, and the broken pods being blown out by teeth fl', and :rel/Listing mechanism, and the 1g the blast from the fan G that passes through ehzunber C, provided withteethc, six-id teeth d this flue. and c being nearer to each other in the row. The sel-oen f may be raised above the beland the rows eloserxigether :is theyapprfmel: 5 tom of flue l", if desired. the bottom of the said plunger and ehzunber.

Any system of pulleys and belting may be substantiellyes shown and described, fund fer 2o used to drive the fm1. and reciprocate the the purpose specified. plunger; hence I do not confine myself to the In testimony whereof l hereunto m'lix my Spelee manner shown. signature in presence ofi' two witnesses.
